# What is single-ended and differential ended?

## What is single-ended and differential ended?

A differential voltage is “floating”, meaning that it has no reference to ground. The measurement is taken as the voltage difference between the two wires. A single-ended measurement is taken as the voltage difference between a wire and ground.

### What is single ended signaling and differential signaling?

Single-ended signaling is the simplest and most commonly used method of transmitting electrical signals over wires. The main alternative to single-ended signaling is called differential signaling where the two conductors carry signals equal in magnitude but of opposite polarity.

#### What is a single-ended output?

A single ended output is a signal that is always referenced to the shield (which is typically earth ground) on the output connector. This is the most common type of signal output or input. A complimentary output has both the channel and the channel(NOT), or an inverted (180 degrees out) version of the channel.

What is a single-ended measurement?

Single-ended measurement is done by measuring one potential with respect to a fixed common reference. In general, you may use single-ended measurement when there are only two output leads and one lead is connected to a known reference potential (a shared return or common for example).

What is a single-ended input?

A single ended input measures the voltage difference between a wire and the ground. Single ended inputs can suffer from noise as the wire that carries the signal picks up electrical background noise. The signal on a single ended input could also be subject to ground loops.

## What is a single ended input?

### What is the difference between single ended and differential analog inputs?

Single-ended inputs are lower in cost, and provide twice the number of inputs for the same size wiring connector, since they require only one analog HIGH (+) input per channel and one LLGND (-) shared by all inputs. Differential signals require signal HIGH and LOW inputs for each channel and one common shared LLGND.
